I have a 500 HO motor (( Internal Combustion Engine ? )) and want to get it in the 350. I have a small 1 acre track in my backyard and the 2 stroke is just too loud for the neighbors so it's time to quiet it down and get a little more low end torque too. I found some old pictures of a similiar conversion but no other info. Has anyone here worked through one of these conversions before?

Thanks

What are your plans so far?

You will want to build a good Engine mount maybe try and follow the original mount, you need to maintain your belt alinement's perfectly, the Engine cant twist or rock around under load either.

I am just getting started on this and have a project to finish first (rebuilding a Cannondale 440 motorcycle Engine for my dirt bike) but I wanted to get all of the pieces I need first. I have the motor (( Internal Combustion Engine ? )), the oil tank, and a Polaris clutch. I have a 102c clutch in the Odyssey now and I don't know if it can be used for the Polaris motor (( Internal Combustion Engine ? )). I want to find out if I can use a 350 belt or if I need to use a Polaris belt. I like the alignment tool I saw in one of your explanations and will make something similiar once I know what I need to work with.

Thanks

did you ever get your reciept???

IF you use the clutch off the Ody Engine (taper should be the same) you need to blueprint the offset and center to center distance between the crank and the trans input shaft then copy it with your old clutch on the Polaris Engine this will also allow you to run the 350 belt...

You read my 440 saga on the Engine install if you look at the pics then ask yourself "why he do that" keeping in mind plumb level and square I think you will get it.

I did get a receipt eventually...

Hoser,
Thanks for the info on the shafts. I'll work out the alignment like you did before.

Thanks again.

Please keep us updated were on the edge of our seats

Hopefully you won't fall off asleep...
